[QUOTE="Conder101, post: 4501008, member: 66"]I think he is asking if there is a link that will take him someplace that explains what electrotypes are and potentially how they are made. Quick, simple explanation of an electrotype, two metal shells (obv and rev) that are filled with a low melting point lead alloy and joined together. Quick and simple explanation of how they are made: Take a small block of wax, heat coin a little and press into the wax. Remove coin from wax block, this give you a negative of the coin surface. Do the same in another block for the other side. Dust negatives with graphite powder to make them electrically conductive. Plate the negatives with copper, silver, or gold depending on the coin. Make the plating thick enough that it will have some structural strength. Melt the wax. You now have two shells each showing an exact replica of one side of the coin. Just fill each shell with the low melting point lead alloy. Put the two pieces together and apply just enough heat so the alloy starts to melt bonding the two sides together. Clean up the edge between the shells. Electroplate the finished piece with the proper metal. You now have a lead filled metal shell that looks exactly like the original coin. I could go into more depth but that should give you the basic idea.[/QUOTE]
